Fixes from the post-migration code review (3 major, 4 minor): - worker: heartbeat between every drained command so a long queue can't starve proof-of-life into a false reap; worker_stale_after default 60s -> 300s (one slow sync/login command must not look like a crash) - repository.create_run: enforces one running run per agent atomically (agent-row FOR UPDATE on Postgres; SQLite's single writer suffices) - two workers claiming resumes for the same agent can no longer both launch claude on one session; resume surfaces the loss loudly - headless._settle: upload the final session archive BEFORE marking the run finished - a resume claimed the instant a run leaves 'running' materializes from session_archives, and the old order let it race an incomplete archive into needless context re-injection (found as a test flake, real in production) - store.tsx: generation token drops in-flight loadRun writes after the user switches runs (run A's events/log/checkmark no longer land on run B), plus id-keyed dedup on event appends from overlapping polls - credsync: credential files written 0600 from the first byte - headless: seq counter locked (reader thread + supervisor both emit events); proc.stdout closed after reader join - login: submit pins to the latest CLAIMED login_start (a still-running one previously pinned to the wrong worker) Suite 296 green (new: create_run conflict coverage); reaper tests track the new staleness default.

"""Slot-aware command claiming: a worker at max_concurrent_runs must leave run-starting

commands queued (for a less-loaded worker) while still processing everything else. Slot
|
|
accounting is DB-driven — this worker's ``running`` agent_runs rows — so it needs no

in-memory registry and is exercised here without real subprocesses."""
